EINAB G. HALTJQUIST, OF EDWARDSVELE, ILLINOIS, ASSIGNOB TO COMMONWEALTHv STEEL COMPANY, OF ST. LOUIS, MISSOURI, A CORIOTION OF MISSOURI.

RAILWAY TRUCK.

Application filed August 26, 1924. Serial No. 734,197.

To all whom it may concern:

Be it known that I, EINAB G. Hemmer, citizen of the United States,residing at Edwardsville, Illinois have invented a cerlmprovement inRailway Trucks, of which the following is a specification, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to railway rolling stock and consists in animproved truck construction.

My invention is particularly adapted for use in engine trucks of thetype which carry the locomotive body through rockers or other supportingelements which must be mounted on the truck below the level of the topthereof in order to lower the point of support.

i The object of my invention is to provide a transom and truck frameconstruction of light weight yet possessing the strength necessary totake care of the load carried as required by the type of body supportsre- In the accompanyin drawings which illustrate a preferred em odimentof my invention, I show a four wheel engine truck having an integral onepiece frame, including wheel pieces, pedestals, transoms, and

rocker supporting members, and in these drawings- Figure 1 is a verticallongitudinal section through the center of a truck.

Figure 2 is a vertical transverse section.

on line 2-2 of Figure 1 and is drawn on a r scale.

igure 3 is a vertical transverse section on line 33 of Figure 1 and isdrawn onthe same scale as Flgure 2.

The truck is equip ed with the usual wheels 1 and axles 2. t will beunderstood that the axle journals are provided with journal boxes, notshown, upon which rest the equalizers 3 which carry springs 4 upon whichare mounted wheel pieces 5 of the truck frame. a i

Wheel pieces 5 are connected at spaced points by transoms, each of whichconsists .in a vertically-disposed body wall 7, the top of which issubstantially on the level of the top of wheel pieces 5, although anupward projection 8 of-limitedlength may be provided, if desired. Thetop of the transom is provided with a reinforcing flange 9' extendingoutwardly and united with wheel pieces 5.

The ends of the transoms are of the same of this shelf between thetransoms are connected with the bottom of the wheel pieces by verticalwalls 11 and these walls may be reinforced by suitable ribs 12. Thedepth of these ribs 12 is limited because of the space requirementof thebody supporting rockers 13 mounted upon shelf 10.

Due to the space requirements of rockers 13 and the resulting connectionbetween the ends of shelf 10 and the wheel pieces there is a tendency'for the frame to fail at the junction of the shelf and walls*or of thewalls and wheel pieces. To resist this tendency, I rovide transom bodywalls 7 with. reinforcing flanges 14 located on the outside thereof andextending from points near the center of the transoms upwardly andoutwardly to the wheel pieces with which the ends of the flanges 14 areunited. Preferably the outer edge of each flange 14 is provided with areentrant rib 15 which merges with wheel pieces 5 and also mer es withthe outer edge of the corresponding ange 9, and ribs 15 may be sha d asindicated at 16 in Figprovided for the locomotive body 17 While I haveshown my invention as applied to a four wheel locomotive truck adaptedfor particular body supporting elements, it is obvious that my inventionmay be applied to other truck construction with suitable modificationsin the details thereof without departing from the spirit thereof asclaimed.

I claim:

1. In a railway truck transom, deeper at its center than at its ends, ahorizontal load carrying flan e, and an inclined reinforcing flangeextending from a point on said transom intermediate the ends of saidhorizontal flange toward the end of the transom.

2. In a railway truck transom, deeper at its center than at its ends, ahorizontal load carrying flange near the bottom of the transom, andinclined flanges extending upwardly and outwardly from a point on saidtransom intermediate the ends of said horizontal flange.

3. In a railway truck transom, a load carrying flange extending fromnear the center of said transom disposed independently of the line ofstrain in the transom roduced b the load, and a reinforcing ange extening from near the center of said transom disposed along said line ofstrain.

4. In a railway truck transom having a. vertically disposed body wall, aload carryin flan e on one side of said wall disposed in open entl ofthe line of strain in the transom ro uced by the load, and a reinforcingange on the other side of said wall disposed along said line of strain.

5. In a railway truck transom, a vertically disposed body wall, ahorizontal load carrying flange on one side of said wall near the bottomthereof, a horizontal flange on the other side of said wall near the topthereof, inclined flanges on the latter side of said wall extendingupwardl and outwardly from near the center of t e transom, and a returnrib on the edge of said inclined flange united with said top flange nearthe ends thereof.

'6. In a railwa truck, an integral frame comprising whee pieces, atransom connecting said wheel pieces and extending below the level ofthe same, a horizontal flange on one side of said transom and below thelevel of said wheel pieces, and an inclined flange on the other side ofsaid transom extending inwardly and downwardly from each of said wheelpieces.

7. In a railway truck, an integral frame comprising wheel pieces, atransom connecting said wheel pieces and extending below the level ofthe same, a horizontal flange on one side of said transom and below thelevel of said wheel pieces, and an inclined flange 0n the other side ofsaid transom extendin inwardly and downwardly from each of sai wheelpieces and rovided with a reentrant rib paralleling sai transom andunited with said wheel pieces.

8. In a railwa truck, an integral frame comprising whee pieces, atransom connecting said wheel pieces and extending below the level ofthe same, a horizontal flange on one side of said transom and below thelevel insane of said wheel pieces, and an inclined flange on the otherside of said transom extendini inwardly and downwardly from each. ofsaidwheel pieces and provided with a. reentrant rib varying in depth anddeepest near said wheel pieces and united therewith.

9.
